Background on Mine
Black Butte Coal Company (BBCC) was formed in 1974 and began shipping coal in 1979. BBCC is a surface coal operation utilizing dragline and truck/shovel equipment. Coal is mined from three active mining areas and is transported to our unit train loading facilities, either directly by over-the-road truck or on overland conveyor systems. Unit train loading operations are maintained seven days a week. Each train loaded is sampled, weighed, and flood-loaded. In addition, BBCC has the ability to produce a specialty coal for use in the local industrial market.
Black Butte produces coal from three active mining areas. As such, we have the advantage to adjust coal quality and can provide a complete custom blending capability in order to match our coal to the specfic needs of customers. Black Butte employs the use of an independent commercial testing lab on-site in order to provide quick coal quality results to our customers. Black Butte's goal is to match our product and services to our customers' needs.
